My friends with an IG and concrete deck similar in size to yours have grass and dislike it. It gets soggy and muddy very quickly. They're now planning a border of small, smooth rocks between the concrete and the lawn. That might be an option for your place.
My vote similar to Anna's. I have 2'" or so river rocks on two sides of pool inside the fence and another side between decking and house. They won't get tracked into the pool like pea gravel does. Make sure they are large enough that they won't get stuck in any hose line for vacuum, or picked up and wedged in the bottom opening by a cleaner such as Polaris suction or pressure. Make sure they are bigger than the skimmer pipe opening; kids will be kids. My dogs drop the river rocks into the pool, among many other things.
I have a cut out in deck where there once were large trees. One edge of it is < 30" from edge of pool. This is along the way to and from the yard. I've tried many things in there including mulch and various sizes of rocks. Mulch does get tracked into pools by dogs so probably by little feet too. I have yet to decide on a permanent solution but for past three summers I've covered that area with rubber mulch.

It's only been about 20 years since the trees came out.

At HD there were only two color choices brick red or dark brown. I don't like either but chose the dark brown. The rubber mulch feels good under foot, doesn't blow around as other mulches and doesn't track around as much as other mulches. The doggies like to lie there when it is shady. But the dogs do stir it up and on to the deck when they run over it. It doesn't usually get into the pool even in high winds. I just use the small battery powered leaf blower to blow them back into the cut out. That works better than broom as they don't slide as easily as other mulches. If the rubber mulch ends up in pool it floats so you don't have to worry about it going down a main drain.
My big, wide railroad tie steps, more like landings, going down the hill to under deck, to wild areas, and path to a small barn way on down the hill, are filled with pea gravel. The steps start about 10' from pool edge with the largest part of pool decking between steps and pool. The pea gravel gets shuffled up onto the decking and carried by doggie feet onto decking with some of it occasionaly ending up in the pool. And it hurts when you step on one, on Kool Decking, while barefooted.
Even with our high winds (20 mph is a gentle breeze) we don't have much problem with cut grass in the pool. The doggies are in and out of the pool all day romping in between in the grass and silt. The day the mowers come I make sure the pump is running, skimmer sock in and a cleaner running. By the end of the day the grass is in the skimmers.
The grass-in-pool issue might be very related to what type of grass you have.
I don't want white rocks around our pool as our setting is "woodsie" but the river rocks are a great disguise for the snakes and darker than I would prefer. I'm looking into tumbled glass rocks in colors that offer less disguise for the snakes in the area between the decking and house. Purchased in large quantities brings the prices down considerably. If you want to go with colors there are many, many choices.
